Same issue here, with the latest update installed. I know it's not the end of the world, but it is annoying to have to filter twice every time I start Studio in order to get the correct results 

That is exactly my point. Especially considering it did work before, albeit a long time ago.

As to Alison Field's 'solution': that is not a solution. I (and others with me, I take it from the messages in this thread) mark projects as completed to be able to find them again quickly should a client have some questions. I only remove projects when I know they are truly finished and the client is happy with the result.
Removing the projects from the list entirely results in having to browse the client, sub-client and project folders in File Explorer to locate the specific project, instead of opening the 'completed' section and reverting the project to 'in progress' ... which I assume is what the feature was developed for in the first place.

Ah well, I live in hope that it will be resolved one day ... but judging by the (lack of) speed, I will not hold my breath
